I encoded video with xvid 176x144 15fps simple profile 1, audio aac 64kb/s with FAAC and muxed everything into 3gp file with YAMB.
Nokia Media Player plays it fine, but on the phone there is no sound.
I also tried to make 3gp with amr sound but the result was the same.
I had similiar problem with Im TOO 3gp converter, for some reason one file had sound others didn't.
Can anybody help me about that? Are there any A/V streams or 3gp muxing restrictions?
